"German admits to 'assaulting, raping 1,000 women' ". Why such Leniency in Punishment ?

Yes, it is reported that he has admitted to raping 1000 women. Maybe he is just bragging. And who told you that he has been served a 15 year sentence. The trial has just begun. I don't understand why you are associating Christianity to the trial. He will get a fair trial without any political interference, as in India, and he will get a harsher punishment than the punishment in India. Judiciary there does not allow politicians or Religion to interfere in its process, unlike in India.
